Letterbox Lab

Everything you need to play with science, straight through your letterbox!

Letterbox Lab is the result of an imaginative reinvention of the children’s science kit to be more convenient, more colourful, more fun and more educational. Our mission is to help people have fun playing with science. We do this by devising and curating awesome science experiments, then flat-packing them and putting them through letterboxes.

Playing with Letterbox Lab, your child will dabble with colour-changing chemistry, paint with light, invent slippery slimes and even launch rockets!

But it’s not enough for our kits to be awesome and fun for kids, we also make them simple and convenient as possible for parents. We don’t want you going to the post office to collect the boxes or going to the shops to buy extra materials, so we fit everything needed to do the experiments into a box that fits through most letterboxes. We also know that children aren’t going to read black and white, text-heavy instruction books, so our instructions are full colour comic-books, supplemented by videos.

Thanks for visiting our page, and happy experimenting.
